January 16, 1933 Claims. (Cl. 244-17) The present invention relates to aflying ma chine, more particularly tn flying machine having apneumatically operated rotor, a blower for supplying the operating airfor said rotor, a body,

and an air conduit connected with said body for connecting said blowerwith the atmosphere.

This application is a divisional application oi? my application Ser. No.706,090 filed Jan. 10, 1934.

in the provision of a flying machine having a pneumatically operatedrotor, a blower a body,

and an air conduit within said body for conducting the operating air forsaid blower and said rotor.

A further object of this invention resides in the provision of a flyingmachine having a pneumatically operated rotor, a blower, a body, and anair conduit within said body for conducting the operating air for saidblower and said rotor,

. and having a motor for driving said blower and whereby air circulatingthrough said conduit is used for cooling said motor.

Another object of this invention is to provide a flying machine having apneumatically operated hollow rotor and guide means within said rotorfor distributing and directing the operating'air within said rotor.

Further and other objects of the present invention will be hereinafterset forth in the accompanying specification and claims and shown in thedrawing which, by way of illustration, shows what I now consider to be apreferred embodiment of my invention.

In the drawing:

Fig. l is a part sectional view of a flying machine according to thepresent invention.

- Fig. 2 is a part sectional view of a modified flying machineaccordingto the present invention.-

Referring more particularly to Fig. 1 of the drawing: 33 represents a.hollow rotor having wings provided with apertures 34 and 35 throughwhich air is either blown out of or taken into the interior of the rotorwings. A motor 38 having a cooling jacket is located in the lower rearpart of body 31 which has a saddle-shaped concavely curved back and acompartment 36 extending forwards. By means of gear 39, coupling 40, and

. shaft 4!, motor 38 is connected with and-drives Rotor 331s carried bythe fuselage by 'means of the'axial and radial bearing 46. Theair istaken in through channel 41 provided within body 31 v and is forced byblower 42 into the hollow rotor 33 and leaves this rotor through theapertures 34 and/or 35 which are placed at the rear edge of.

the rotor wings. The air flow can also be reversed and the air taken inthrough openings located near the front edge of the rotor wings anddischarged through channel 41. In both cases, the air passes through acooler 48 which is connected with the cooling jacket of motor 38byconduits I26 and I2! and acts as cooler for the cooling agent-of themotor. I

Fig. '2 illustrates an embodiment of my'invention using the pneumaticreaction type rotor drive guide 55 for the air is provided in theinterior of rotor 49.

While I believe the above described embodiments of my invention to bepreferred embodiments, I wish it to be understood that I do not desireto be limited to the exact details of design and construction shown anddescribed, forobvious modifications will occur to a person skilled inthe art. I

2. In a flying machine, a body having an outer surface, a pneumaticallyoperated propeller rotatably connected to the fore end of said body andhaving hollow wings producing lift and propelling power for said flyingmachine and consti tuting a unit located outside of and substantiallyseparate from said body. blower means air con-' ductingly connected withthe interior of said wings, an air channel formed through said body,

and having a rear end which opens remote from} said propeller at theupper surface of said. body.

3. In a flying machine, a body having an outer surface, a pneumaticallyoperated propeller rotatably connected to the fore end of 'said body andhaving hollow wings producing lift and propelling power for said flyingmachine and constituting a unit located outside of and substantiallyseparate from said body, a blower means air conductingly connected withthe interior of said wings, an air channel formed through said body,said channel having a fore end which terminates in said propeller andcontains said blower means, and having a rear end which opens remotefrom said propeller at the outer surface of said body,-

and a power motor connected with and drbling said blower means and beingalso located in the fore end of said channel, and being cooled by airpassing through said channel.

4. In a flying machine, a body having an outer surface, a pneumaticallyoperated propeller rotatably connected to the fore end of said body andhaving hollow wings producing lift and propelling power for said flyingmachine and constituting a unit located outside of and substantiallyseparate from said body, a blower means air conductingly connected withthe interior of said wings, an air channel formed through said body,said channel having a fore end which terminates in said propeller andcontains said blower means, and having a rear end which opens remotefrom said propeller at the outer surface of said body, and a power motorconnected with and driving said blower means and being located in saidbody outside of said channel, a cooler located in said air channel andbeing cooled by air passing through said channel, and circulatingconduits connecting said motor and said cooler for circulating a coolingagent through said motor and cooler.

5. In a flying machine, a body having an outer surface, a pneumaticallyoperated propeller rotatably connected to the fore end of said body andhaving hollow wings producing lift and propelling power for said flyingmachine and constituting a unit located outside of and substantiallyseparate from said body, a blower means air conductingly connected withthe interior of said wings, an air channel formed through said body,said channel having a fore end which terminates in said propeller andcontains said blower means, and having a rear end which opens remotefrom said propeller at the outer surface of said body, and a power motorconnected with and driving said blower means and being located in saidbody outside of said channel, a cooler located adjacent to said rear endof said channel-and being cooled by air passing through said channel,and circulating conduits connecting said motor and said cooler forcirculating a cooling agent through said motor and cooler.
